1. An initially confusing aspect of cancer is that it can be
caused by a range of different effects, from asbestos to infections
by some viruses to UV radiation and inheritable defects. What is
the current scientific view on how to explain this property of
cancer?
Group of answer choices
Cancer universally involves the mutation (and/or inactivation)
of genes, and these mutations can be caused by a variety of
effects.
Cancers can be classified into distinct types based on the agent
that caused it.
This property of cancer remains largely unexplained.
Cancer emerges through a process that always involves a number
of independent damaging events to occur.
2. Use mutations in genes encoding proteins that are needed
to activate apoptosis as an example of the “loss-of-function”
character through which tumor suppressor genes contribute to
cancer.
Group of answer choices
Cancer cells often have lost the ability activate apoptosis, and
thus avoid being destroyed by the activation of apoptosis based on
their aberrant properties.
Apoptosis is needed to trigger cell growth.
Excessive activation of the apoptosis pathway contributes to
cancer.
Cancer cells often modify the process of apoptosis to meet their
needs.
